and useful Improvements in Thill-Couplings,

of which the following is a specification.

My invention relates to improved means of coupling t-hills to vehicles; and it consists of certain new and useful features of construction and combinations of parts, hereinafter described, and pointed out in the claim.

Referring to the accompanying drawings,

which form a part of this specification, Figure 1 is a View in isometric of the disconnected parts of a thill-coupling embodying my invention. Fig. 2 is a side view of the same operatively connected together.

Like letters of reference indicate corresponding parts throughout the several views.

A is a draw'shackle, having a transverse pintle-bearing A therein and a key-seat A narrowest at the top thereof and opening into the pintle-bearing A.

B is a key adapted to be slid into the keyseat A3.

B is a spring connected with the key B in any suitable manner.

0 is a shaft-eye, provided with a couplingpintle 0, adapted to engage with and be disengaged from the pintle-bearing A through the open key-seat A and having the jaws 0 inserting the ends thereof through the holes A therein.

The shaft-eye O is shown in solid lines in Fig. 2 in the only position at which the keyB can be inserted into and Withdrawn from its seat A in the draw-shackle. The dotted lines 5 in the same figure indicate the normal position of the shaft-eye 0 when in use.

The sole office of the spring B is to prevent the thill-couplingfrom rattling,- and it may be used or not, as desired.

I Claim 7 The combination of the shackle A, having a partially-circular recess A opening into a key-seat A and the shaft 0, provided with the pintle O and the rearwardly-extending jaws G with the key B, reduced in size at the center and provided with a spring 13' around said reduced center, all substantially as shown and described.
